Open source code projects I've worked on

Apache MXNet

Contributed to the Apache MXNet project. Building capabilties in the deep learning framework to allow for reliable and performant deep network deployment on IoT, mobile and edge devices.

Android Location Tracker

Code for a server that automatically collects a users Android location history and exposes and API to query it, along with frontend code for a map to display location information in the browser.

Sonic Bar Code

Code from HackMIT 2013 for a server to create ultra-sonic "bar codes" associated with URLS and an iOS app capable of discovering them.

Pfast and Pfurious

Code to continuously scrape shuttle location data for the Harvard shuttles from the web app Trans-Loc.

Seam Carving

Code from my CS51 final project to resize images in a content aware manner using a seam carving algorithm.

Research I've published in machine learning, digital privacy and security

Stochastic Activation Pruning for Robust Adversarial Defense

A paper presented at NIPS 2017 in the Machine Deception Workshop introducing a technique to allow pre-trained networks to become less suseptible to adversarial attacks by using a novel stochatic "dropout" procedure applied to activation tensors at prediction time, which maintains model accuracy while adding robustness to misclassifying adversarially preturbed inputs.

Tensor Contraction & Regression Networks

A paper presented at NIPS 2017 and winner of best poster in the MLTrain Workshop, showing that by replacing flatten and fully connected layers in convolutional neural networks with novel tensor contraction and regession "layers", we can expliot the natural multi-linear structure of activation tensors and reduce the number of parameters needed to achieve state of the art accuracy in popular image classification architectures, including Resnet and VGG.

StrassenNets: Deep Learning With a Multiplication Budget

A paper presented at NIPS 2017 in the MLTrain Workshop, introducing the use of learnable sum product networks in place of general matrix multiply operations in convolutional neural networks, allowing for a significant reduction in the number and precision of multiply accumulate operations needed to run accurate prediction with these models.

Tensor Contraction Layers for Parsimonious Deep Nets

A paper presented at CVPR 2017 in the Tensor Methods for Computer Vision Workshop, introducing a new deep network "layer" based on applying the Tucker tensor contraction process to activation tensors. We find that this allows for significant dimensionality reduction of the activation tensor, yielding more efficient model representations without impacting accuracy.
